Drying Cycle : Purified (Moisture and oil free) air from the compressed air system, Passing through one of the tower filled with Molecular Sieves (Zeolite type). The sieves selectively adsorbs nitrogen, allowing oxygen to pass through at the desired purity level.

Regeneration Cycle : During regeneration cycle, the sudden depressurisation brings out nitrogen molecules strapped in the sieves pores to the surface of the beads. Small portion of oxygen from the drying tower is passes over the sieves through the regeneration orifice. This results in complete regeneration of Molecular Sieves. The automatic cycling of the adsorption and desorption between the two beds enables the continuous production of oxygen. Detailed design of process parameters followed by extensive validation has resulted in consistant performance in Oxygen Series. Highly reliable PLC based controller with digital display of generator operations.
